Abstract

A column is indented around the outside by moving the said column (1) initially between two rollers (5, 5-5', 5') of in each case a pair of indenting rollers arranged one behind the other and is indented on two opposite sides of the column. Subsequently, the pairs of indenting rollers (5, 5-5', 5') are moved transversely with respect to the said first direction of movement of the column towards each other, the pairs of rollers clamping the column between them and indenting from the edges on the two other opposite sides of the column, whereupon the column is moved through between the two indenting rollers of each pair of indenting rollers (5, 5'-5,5') in a second direction of movement, and thus an indenting around the outside is produced. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung nach den Oberbegriffen der Ansprüche 1 und 3.The invention relates to a method and a device according to the preambles of claims 1 and 3.

Die Kerbung von Tonstrangstücken im Schnittabstand erfolgt, um saubere und gefaste Schnittkanten beim nachfolgenden Schneiden der Formlinge zu erzielen. Die Schneidedrähte tauchen beim Schneiden in die Kerben ein.Clay strand pieces are notched at the cutting distance in order to achieve clean and bevelled cutting edges during the subsequent cutting of the moldings. The cutting wires dip into the notches when cutting.

Ein Verfahren und eine Vorrichtung der in den Oberbegriffen der Patentansprüche 1 bzw. 3 aufgeführten Art ist aus der DE-AS 2832 167 bekannt. Die Vorrichtung weist zwei Reihen von Kerbrollen quer zur Bewegungsrichtung des Tonstrangstückes auf, die aus einer ersten Stellung in eine zweite Stellung und umgekehrt auf- und abbewegbar sind und während ihrer Bewegung aus der ersten in die zweite Stellung die Vorderseite und in der zweiten Stellung wahrend der Bewegung des Strangstückes durch sie hindurch die Ober- und Unterseite und während der Bewegung aus der zweiten Stellung in die erste zurück die Rückseite des Strangstückes kerben.A method and a device of the type listed in the preambles of claims 1 and 3 is known from DE-AS 2832 167. The device has two rows of notch rollers transverse to the direction of movement of the clay strand piece, which can be moved up and down from a first position to a second position and vice versa and during their movement from the first to the second position the front and in the second position during the Notch movement of the strand piece through them the top and bottom and during the movement from the second position to the first back the back of the strand piece.

Mit dieser Vorrichtung kann aufgrund der großen Masse des Tonstrangstücks ein präzises Anhalten auf dem ersten Förderer nicht mit Sicherheit erfolgen, so daß eine saubere Kerbung von in der Regel nur 2 bis 3 mm Tiefe, besonders aufder Vorderseite des Strangstückes, nicht immer erzielbar ist, ebensowenig wie auf der Rückseite, weil der Reibungswiderstand zwischen dem Strangstück und dem zweiten Förderer stets größer sein müßte als die durch das Kerben ausgeübte horizontale Kraft, was jedoch nicht immer der Fall ist.With this device, due to the large mass of the clay strand piece, a precise stopping on the first conveyor cannot be carried out with certainty, so that a clean notch of usually only 2 to 3 mm depth, especially on the front side of the strand piece, cannot always be achieved, just as little as on the back, because the frictional resistance between the strand piece and the second conveyor should always be greater than the horizontal force exerted by the notching, but this is not always the case.

Nachteilig ist auch, daß beim Kerben zwar auf der Einlaufseite eine saubere Kerbung erzielbar ist, nicht jedoch auf der Auslaufseite. Dort wird Material in Richtung Schauseite verdrängt, was zur Nasenbildung führt und zu scharfen Kanten, die unerwünscht sind.Another disadvantage is that when notching a clean notch can be achieved on the inlet side, but not on the outlet side. There material is displaced towards the face, which leads to the formation of noses and to sharp edges that are undesirable.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, die eine gleichmäßig gute Qualität ohne Nasenbildung an den Ecken des Formlings erzielen.The invention has for its object to provide a method and an apparatus which achieve a consistently good quality without formation of noses at the corners of the molding.

Diese Aufgabe wird erfindungsgemäß durch die in den kennzeichnenden Teilen der Ansprüche 1 und 3 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing parts of claims 1 and 3.

Die Erfindung stellt sicher, daß durch das Kerben mittels Rollenpaaren bei der Kerbung in der ersten Bewegungsrichtung am Auslauf bestehende Nasen durch die Kerbung in der zweiten Bewegungsrichtung beseitigt werden. Die Kerbung in der zweiten Bewegungsrichtung erfolgt im eingespannten Zustand des Tonstrangstückes zwischen den Kerbrollenpaaren durch Bewegung der Kerbrollenpaare aufeinander zu, so daß kein Auslauf der Kerbrollen aus den gebildeten Kerben mit dem Risiko der Nasenbildung gegeben ist. Bei der Herausbewegung des Tonstrangstückes aus der Kerbeinrichtung mittels des Hubtisches erfolgt das Auslaufen der Kerbrollen über bereits gebildete Kerben, so daß auch hier die Nasenbildung sicher vermieden ist.The invention ensures that by notching by means of pairs of rollers during the notching in the first direction of movement at the outlet existing noses are eliminated by the notching in the second direction of movement. The notching in the second direction of movement takes place in the clamped state of the clay strand piece between the notch roller pairs by moving the notch roller pairs towards one another, so that there is no leakage of the notch rollers from the notches formed with the risk of nasal formation. When the clay strand piece is moved out of the notching device by means of the lifting table, the notch rollers run out over notches which have already been formed, so that here too the formation of noses is reliably avoided.

Die Zeichnung zeigt eine Vorrichtung zum umlaufenden Kerben eines Tonstrangstückes und zum Schneiden desselben in Formlinge. Das Tonstrangstück wird von einem Zubringer mit einem Schieber 2 quer zu seiner Längserstreckung abgeschoben und in eine Kerbeinrichtung 3 gebracht. Die Kerbeinrichtung enthält einen unteren und einen oberen Kerbrollenhalter 4 bzw. 4'. An den Kerbrollenhalter sind jeweils paarweise Reihen von Kerbrollen 5 bzw. 5' angebracht. Die Kerbrollenreihen können in eine Stellung zueinander gebracht werden, die das gleichzeitige Kerben jeweils zwei gegenüberliegender Strangseiten erlaubt. Dazu sind Rollenreihenpaare 5 bzw. 5' auf den oberen und den unteren Rollenhaltern 4, 4' jeweils abstandsveränderlich angebracht und die Kerbrollenhalter 4, 4' mittels einer gemeinsamen und gegenläufig wirkenden Exzenterwelle 7 aufeinander zu und voneinander weg bewegbar. Innerhalb der Kerbeinrichtung 3 ist ein Hubtisch 8 angeordnet, welcher mittels eines Kurbeltriebes 9 heb- und senkbar ist.The drawing shows a device for circumferential notching of a piece of clay strand and for cutting the same into moldings. The piece of clay is pushed off a feeder with a slide 2 transversely to its longitudinal extent and brought into a notching device 3. The notching device contains a lower and an upper notch roller holder 4 and 4 '. Rows of notch rolls 5 and 5 'are attached in pairs to the notch roll holder. The rows of notch rollers can be brought into a position with respect to one another which allows the simultaneous notching of two opposite strand sides. For this purpose, pairs of rows of rollers 5 and 5 'are each mounted on the upper and lower roller holders 4, 4' so as to be variable in distance, and the notched roller holders 4, 4 'can be moved towards and away from one another by means of a common and counter-acting eccentric shaft 7. A lifting table 8 is arranged within the notching device 3 and can be raised and lowered by means of a crank mechanism 9.

Oberhalb der Kerbeinrichtung 3 befinden sich Schneiddrähte 6. Über den Schneiddrähten 6 ist ein Abschieber 11 angebracht, der die geschnittenen Formlinge auf einen Abförderer 12 bringt.There are cutting wires 6 above the notching device 3. Above the cutting wires 6, a pusher 11 is attached, which brings the cut moldings onto a removal conveyor 12.

Die Vorrichtung funktioniert in folgender Weise:
Durch den Schieber 2 wird das Tonstrangstück 1 quer zu seiner Längsrichtung in die Kerbeinrichtung 3 befördert und dort positioniert. Während des Transportes in die Kerbeinrichtung 3 wird das Strangstück durch die an der Eingangsseite gelegenen Kerbrollenreihen 5 und 5' auf seiner Unter- und Oberseite gekerbt, wozu die Kerbrollenhalter 4 und 4' soweit auseinandergefahren sind, daß sie das Strangstück 1 zwischen sich aufnehmen und die Kerbrollenreihen auf Ober- und Unterseite des Strangstückes einwirken können.
The device works in the following way:
The sliver 2 transports the clay strand piece 1 transversely to its longitudinal direction into the notching device 3 and positions it there. During transport into the notching device 3, the strand piece is notched on its underside and top side by the notch roller rows 5 and 5 'located on the input side, for which purpose the notch roller holders 4 and 4' have moved apart so far that they accommodate the strand piece 1 between them and the Notch roller rows can act on the top and bottom of the strand piece.

Nach dem Kerben der Ober- und Unterseite ist das Strangstück 1 stillgesetzt. Nunmehr werden die Rollenhalter 4 und 4' mittels der Exzenterwelle 7 aus der auseinandergefahrenen Stellung in Richtung Mitte des Tonstrangstückes aufeinander zubewegt, wobei die eingangsseitigen Kerbrollenreihen 5, 5' an der Rückseite des Strangstückes und die ausgangsseitigen Kerbrollenreihen 5,5 an der Vorderseite des Strangstückes zum Eingriff gelangen und diese Seiten von den äußeren Kanten her kerben.After notching the top and bottom, strand 1 is stopped. Now the roll holder 4 and 4 'are moved towards each other by means of the eccentric shaft 7 from the extended position in the direction of the center of the clay strand piece, the rows of kerf rolls 5, 5' on the input side at the back of the strand piece and the row of notch rollers 5.5 on the front side of the strand piece Engage and notch these sides from the outer edges.

Nach diesem Vorgang wird das Strangstück 1 durch den Hubtisch 8 zwischen den beiden Kerbrollenpaaren 5,5 ; 5',5' hindurch nach oben bewegt und im Bereich der Schneiddrähte 6 geschnitten. In der obersten Stellung des Hubtisches 8 übernimmt der Schieber 11 den Abschub der geschnittenen Formlinge vom Hubtisch auf den Abförderer 12.After this process, the strand piece 1 by the lifting table 8 between the two pairs of notches 5.5; 5 ', 5' moved upwards and cut in the area of the cutting wires 6. In the uppermost position of the lifting table 8, the slide 11 takes over the pushing of the cut moldings from the lifting table onto the conveyor 12.
